JBL 670GTi 6.5" Components

JBL 670GTi Component System

We know why you're here. Those other speakers, which are actually pretty nice, just aren't good enough. You've got discerning auditory taste, and this is where you've landed: Checking out the JBL 670GTi 6.5" component system.

670GTi

Years of audio expertise have led to the meticulous engineering that's gone into these absolutely premium speakers. Among JBL's reference-class systems - the finest of the fine - the 670GTi will set you up to win competitions, make you the envy of your audiophile community and just plain make everything sound about as good as it's going to sound.

From the build quality to the sheer beauty of these speakers, JBL's 670GTi represents everything for which car audio enthusiasts strive. The crossovers, the tweeters, the woofers, all of them come together to truly satisfy the most fastidious listeners. Take the time to learn a little more, but we already know your mouse is on the Add to Cart button.

1-inch tweeters bring out the highs like never before

A new reference level...


... for your ears and expectations. JBL's 670GTi system employs some of the lowest distortion midwoofers the company has ever produced. With a neodymium magnet, Nomex spider, Kevlar cone and copper polepiece cap, all the pieces work together to give some of the most accurate in-vehicle sound reproduction ever. Even the voice coils in the 1-inch tweeters are oversized to increase power handling and leave distortion behind.

Connect those with a precision crossover - built with heavy-trace printed circuit boards to maximize heatsink and power handling - and your system will sound better than you ever thought it could. Everything inside from the air-core inductors to the polypropylene capacitors give you more than you'd ever expect from your car audio.

Grab this set from here at Sonic Electronix. Sure, we'll thank you, but we're sure you'll thank us, too.

Why you want these:

  • One of JBL's lowest distortion drivers ever
  • Crossovers with home audio inspired technology
  • 1" textile dome tweeters are capable of reproducing 30k Hz
  • Overhung voice coils in midwoofers increase power handling

    Speaker Specifications

    Series
    This is the manufacturer product line of speakers.
    Gti (JBL)
    Priced Per
    Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
    Pair
    Speaker Size
    Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
    6-1/2"
    Design
    The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
    2-way Component System
    Tweeter Design
    Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
    Dome
    Tweeter Composition
    Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

    PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

    Textile
    Woofer Composition
    Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
    Kevlar Fiber
    Woofer Surround
    A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
    Nitrile Butadiene Rubber (NBR)
    Peak Power Handling
    Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
    600 watts
    RMS Power Handling
    The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
    150 watts
    Sensitivity
    An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
     
    Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
    92 dB
    Frequency Response
    The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
    50 - 30,000 Hz
    Impedance (Per Voice Coil)
    The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
    4 ohms
    Shallow Mount Installation
    This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

    Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

    No
    Top-Mount Depth
    The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
    3-1/16"
    Cutout Dimensions
    Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
    5-1/16"
    Speaker Grilles
    A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
    Yes
    Number of Speakers
    This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

    Please refer to the product image and description for further details about the speaker.

    2 Woofers + 2 Tweeters

    April 24, 2016

    This is my first review ever. I am so thrilled to write this review. First of all, this is my first time using JBL products and boy am I glad! I have these bad boys hooked up active to a p8004 rockford amp using my headunit dex p99rs.
    The level of fidelity of these speakers cannot be matched, and they go very loud and are crystal clear.
    The music is so vibrant and alive to say the least, and stays so through out full volume.

    I choose JBL honestly because I am an SQL guy, these speakers far exceeded my expectations. In the past I used 2 components upfront and 2 6×9 in the back. The current setup is only a component of these upfront and it sounds much louder than my previous setup.

    The speakers offer tons of technology and a properly oversized voice coil for lots of power handling. The tweeter is ruler flat all the way to 30,000 hz and is not fatiguing to listen to. The midbass driver is hungry for power and though crossed at 65 hz sounds crystal clear on high volume playing with music filled with bass.

    If you are serious about sound quality and you like music to be loud look no further these components are a jewel for their price range. Well done JBL!! Keep up the amazing work.
